Value Collection R63091368 Hex Head Cap Screw Brass

Product Description

The VALUE COLLECTION R63091368 is a hex head cap screw designed for general fastening applications across mechanical, plumbing, and HVAC assemblies. It features a 5/16-18 thread size with a Unified National Coarse (UNC) thread standard, a length under head of 1-1/4 inches, and a 1/2-inch hex drive. The fastener is machined from brass, making it well suited for applications where corrosion resistance, electrical conductivity requirements, or compatibility with dissimilar metals is a factor. Installation is straightforward with a standard hex wrench or socket. These screws are sold in minimum order quantities of 5.

This cap screw is appropriate for use in residential and light commercial installations where a brass fastener is specified. Common applications include pipe flange connections, electrical enclosure hardware, HVAC equipment panels, pool and spa equipment assemblies, and other environments where steel fasteners may corrode or cause galvanic issues. Its UNC thread form ensures broad compatibility with standard tapped holes and nuts in inch-measurement systems.

Key Features

• 5/16-18 UNC thread for compatibility with standard inch-system tapped holes and nuts
• 1-1/4-inch length under head suits medium-depth fastening applications
• Brass construction provides corrosion resistance and galvanic compatibility
• 1/2-inch hex drive accepts standard hex wrenches and sockets
• Minimum order quantity of 5 units supports small service and repair jobs

Compatibility

Designed as a standard inch-series hex head cap screw for use in any application requiring a 5/16-18 UNC brass fastener with a 1-1/4-inch length under head.

Installation Notes

Install using a standard 1/2-inch hex wrench or socket driver. De-energize or depressurize any equipment before replacing or installing fasteners in live assemblies. Apply thread sealant or anti-seize compound only when specified by the equipment manufacturer. Do not overtighten brass fasteners, as the material is softer than steel and susceptible to thread stripping.
